A Study Shows That Tea Tree Oil May Alter Hormonal Levels
In 2007, tea tree oil was under risk of being banned by the European Union, on the grounds that it was unsafe and unstable and that it may interfere with normal hormonal functions.
There have actually been three case reports of gynaecomastia, the enlargement of breasts in young boys, caused by topical application of tea tree oil. However, when the boys discontinued tea tree oil use, their condition went back to normal and the enlargement disappeared.
Some American researchers, in fact, think that certain oils may affect hormones and that continuous use of these oils may alter hormonal function.
However, cosmetic products that use the tea tree oil in concentrations of less than 1 per cent are considered safe.
